Update git submodules

* Update docs/submodules/integration/test from branch 'master'
  to 786172d61b05f5bba4d64800cfc2065b296b5ec1
  - Remove check for ownership change

    The "Partition And Heal" and "Global Rpc Freeze" expect the
    owner not to change after rejoin but akka may report a spurious
    unreachable member event that can cause an owner change after rejoin.
